It can be easily propagated by division in the spring. Pull rhizomes apart gently, making sure that each piece has at least two or three leaves attached. Plant individual pieces in 3 inches pots of either of the recommended potting mixture, burying each piece at the same depth as the entire rhizome was planted. Try not to apply any fertilizer to the newly potted rhizome sections for three months.
